Hehe, a 386 is the newest PC I'd keep (well, maybe a 486). Everything after that is no good. This excludes the newer stuff though (2002 and older). I keep that stuff because it's useful
You'd be amazed with what you can do with this stuff. Not as useful as a Mac though. I collect a wide variety of computers, not just Macs. This one will probably end up as a testing box for various Software. And it's Small-form factor (almost), so it looks nice.
A couple (low-quality) pictures, before I cleaned it:

Note: the bays are 3.5" ones, not 5.25". It's a lot smaller than the Equity I posted here earlier.
